An aqueous blue ink for use in ink jet printing, the ink being a mixture of a blue dye, a cyan dye, a styrene/acrylic binder, water and ammonia as a volatile solubilizing constituent.
A water base dye ink composition which comprises: (i) water as a solvent; (ii) a carboxyl group containing styrenic resin having an average weight of 1500-30000 and an acid value of 150-300, in an amount of 2-20% by weight; (iii) at least one anionic dye selected from the group consisting of: (a) a metal complex azo acid dye; (b) C.I. direct black; and (c) C.I. acid yellow 110, C.I. acid yellow 127, C.I. direct yellow 100, C.I. 20215, C.I. 20216, C.I. 20230, C.I. 23266, C.I. 23635, C.I. 40002, C.I. 40215, C.I. 42655 and C.I. 42660, in an amount of 0.01-10% by weight; and (iv) an alkali which is volatile at normal temperatures in such an amount as put the ink composition at a pH in the range of 6 to 9.5.
An ink is described, comprising an amine having a boiling point of between about 120.degree. C. and about 200.degree. C., an acrylic binder selected to render the ink filterable, a direct dye or acid dye substituted with at least 3 amino groups, and water.
Ink jet ink compositions consisting essentially of an aqueous carrier medium; an anionic dye; and an anionic polymer have excellent decap and puddling behavior and may be used with a variety of ink jet printers such as continuous, piezoelectric, drop-on-demand and thermal or bubble jet drop-on-demand, and are particularly adapted for use in thermal ink jet printers.
Aqueous pigment dispersions include branched alcohol alkoxylates of formula (I) as set forth in the specification and claims. The total dispersant used may include at least 40% by weight of the branched alcohol alkoxylate. The pigment dispersion is effective for a wide variety of pigments, including, inorganic pigments, organic pigments and carbon black. The pigment dispersions are useful, for example, in paints and other surface coatings.
A textile-printing method imparts ink containing a cyan disperse dye and ink containing blue disperse dye on a cloth such that the cyan ink and the blue ink are at least partially overlapped, thereby forming a color mixture portion on the cloth, wherein a weight ratio of the cyan dye to the blue dye at the overlapped portion is specified in the range of from 10:1 to 100:1.
